CISCO-BERT-MIB

The MIB module to configure and perform Bit Error Rate Testing
        (BERT) on DS3, DS1/E1 and DS0/DS0Bundle interfaces.
        Bit error rate testing and loopbacks are used by carriers
        and ISPs to aid in problem resolution as well as for
        testing the quality of T1/E1 or T3/E3 links.  Tests can
        be run on a full T1/E1 line or can be run on a fractional
        T1/E1 such as single DS0 or a group of DS0s.  By using BERT,
        poor quality links could be detected early.
        BERT enables the user to test the quality of links by directly
        comparing a pseudo-random or repetitive test pattern with
        an identical locally generated test pattern. 
        
        Terminology:
        
        BERT: Bit Error Rate Testing (BERT) involves generating a known
        data sequence into a transmission device and examining the
        received sequence at the same device or a remote device
        for errors.
        
        The use of BERT results in the computation of a bit error rate
        (BER), which is
        		
        		bits received in error
        	BER = ------------------------
        		number of bits transmitted
        
        To perform a bit error rate test using one tester, 
        communications equipment must be placed into a loop-back
        mode of operation and the BERT test can then be used to 
        determine if equipment is operating correctly.
        
        When running a BERT, system expects to receive the same pattern
        that is transmitting.  To help ensure this, two common options
        are available.
        
        - Use loopback somewhere in the link or network.  This can
         be accomplished by putting the line in loop up mode;
         send the pattern; find the BER.
        
        - configure remote testing equipment to transmit the Same BERT
          pattern at the same time.
        
        Typical Sequence in Performing Bit Error Rate Test by the 
        device is given below:
        
        - Loop Up:
        The tester issues special code to force the far end (CPE) into 
        loopback.  Upon recognition of the loop activation request code
        the CPE enters a loop mode in which it returns the port data
        back to the tester.
        
        - Send Pattern:
        After a loop has been established, the tester can generate 
        test pattern toward the CPE and monitor the incoming data.
           
        - Loop Down:
        The tester issues a special code (loop down command) to 
        release the far end from the loopback.
        
        Terminology Used:
        CPE - Customer's premise equipment.  At CPE, following equipment
        is required:
        DSU
        CSU
        Usually DSU and CSU functions are incorporated by vendors
        into a single CSU/DSU unit.
        OCU - Office Channel Unit
        CSU - Channel Service Unit
        A CSU contains the last signal regenerator on the line 
        before DTE and mechanism to put the line into loopback
        for testing from the central office.
        DSU - Data Service Unit.
